The resistance of contact position is maximum (this resistance is contact resistance), according to the fuel factor law (being also Joule's law) of electric current, i.e. Q=
Known to IR.t：When electric current is equal, then the bigger position fever of resistance is higher, therefore in welding, the contact of welding rod is namely
The contact resistance of the contact position of the metallic object connect is maximum, then the electric heating generated at this position is naturally also just most, welds in addition
Item is lower melting-point alloy, is easy fusing naturally.Alloy electrode core after fusing is bonded on welded article body, it is cooling after just
Welding object is bonded in one piece.
